Control Panel Build

I have begun working on the control panel.  First thing I did was layout all of the holes for switches, heat-sinks, twist lock outlet's, & temp probe cables.  I modeled up my box in 3D and included my 2D hole locations.  This allowed me to create nc programs directly from my CAD data.  The control box needed to be machined on 4 sides.  Here is a pic of the control box before machining.  This electrical enclosure is 16"x12"x8"  and was purchased on ebay.

The first side I machined was the front door.  The front panel is where all the switches for the elements and pumps, an e-stop button, a system start button, and a selector switch for selecting between the HLT and Brew Kettle elements.

Next I machined the top of the enclosure.  This is where the heat sinks for the SSR's will go.  I purchased 2 large aluminum heat sinks from ebay.  I could not fit both heat sinks on the top so  I had to shorten one of the heat sinks by one SSR station.  This involved cutting and drilling and tapping new holes in the heat sink.

The bottom is where I machined holes for the twist lock outlets.  This is where the pumps and elements will plug into.

Last is the left end.  This is where the temp probes will enter the control panel.

Here is a pic with all of the switches.

Here is one with the heat sinks installed.

Here is a pic of all the pc's for the inside of the control panel.

Now back to work.
